The Amazing World of Gumball has been somewhere above Teen Titans Go and below Steven Universe / Adventure Time in clever kids shows for me since I found it. I just started watching the most recent season though, and it has vaulted itself up into one of the greatest absurdist art pieces I know of. And I mean absurdism in the real-ass philosophical way, not just absurd humor. Rosencrantz & Guildenstern are Dead level stuff.

Tennant saying "smarter than the smarties and tougher than the toughies!"

Donald apparently having a more active role than occasional guest star!

Theme song is not a hip-hop remix!

And if they're gonna do an origin story, I like that they're grabbing a few elements from the original Barks comics, with the idea that Scrooge has retired but that his nephews reinvigorate his spirit of adventure.

That sounds like Kate Micucci singing the theme song, which is obvious in hindsight. (Though they've apparently also got Lin-Manuel Miranda as Gizmoduck, so Micucci wasn't the only singer they already had in a recording booth.)

Looks like a fantastic cast all around, even beyond the initial announcements. Jim Rash as Gyro, Paul F Tompkins as Gladstone. Margo Martindale as Ma Beagle -- well why the hell not, she already played Ma Beagle on Justified.

It doesn't appear that Magica de Spell has been cast yet; I know the goal here is an all-new cast (aside from Tony Anselmo as Donald) but I'd sure like to see June Foray back if she's up for it. (She is turning 100 in a few months and I don't see any new credits for her since 2014; she hasn't announced her retirement but if she's not doing a lot of work at this point that's pretty understandable. Last I heard she was involved in a new Rocky & Bullwinkle movie (as Rocky but not as Natasha, because reasons) but it's been awhile since I heard anything about that.)

Also digging the comic-book-panels design (course, I am one of those guys who actually liked Ang Lee's Hulk). Reminding people that hey kids, these were comics! is always a good idea. Hope to see Barks's name featured prominently in the closing credits. (And Rosa's, and anybody else whose work they're adapting. Last time I picked up an Uncle Scrooge comic, it was translations of Italian and Scandinavian comics from the '80s and '90s; Disney comics in general and the ducks in particular are still huge in Europe.)
